USA Today reports that the Department of Homeland Security may be wasting millions of dollars deporting immigrants to Mexico.  From the article:

The agency has spent more than $85 million over the past eight years to transport Mexican illegal immigrants far beyond the border in a humanitarian effort aimed at saving lives by deterring migrants from making another dangerous border crossing.

But it has no real way to gauge the value of the program.

While the department defends its repatriation flights, officials chose not to act on recommendations by government auditors to measure whether the program is effective.

Chances are, the vast majority of those being deported were in the US working, paying taxes and trying to improve their lives.  That is a net gain to the US economy; therefore, this program is a HUGE waste of tax payer dollars whether the immigrants make it back to the US or not.
